Please reinstate the company name and password field in the registration. It is illogical to remove it, as all company names will become usernames and the user has to go find the setting area to change his password. This decision to remove it does not make sense.

A recommendation:

Add a drop-down menu that has two options (individual or company). If the company option is selected, the company field should appear so they can enter their company name, and bring back the password fields.
